Afghan Policeman Turns Weapon on NATO, Afghan Forces

A spokesman for NATO’s International Security Assistance Force (ISAF) told ABC News that no one was killed in the attack, which took place in the Achin district of Nangarhar province. The spokesman would not confirm earlier reports that two American soldiers were wounded.

Afghan officials are leading an investigation into the incident, with the ISAF providing support as needed.

At least six American service members have been killed in the past week by their Afghan counterparts or those wearing their uniforms, undermining the trust needed as coalition forces get ready to leave and Afghanistan takes responsibility for its own security.

In Monday’s attack, the Afghan policeman was not wearing a uniform at the time of the shooting, according to the ISAF spokesman. The gunman managed to get away.
